Definitions

  • the invention relates to a switching device for exhaust gas recirculation in an internal combustion engine with a switching flap and a manifold for selectively introducing the exhaust gas from an exhaust pipe into an exhaust gas cooler and in a bypass line which bypasses the exhaust gas cooler.
  • Such a switching device is for example from the EP-A1-1030050 known.
  • the switching device of this document consists essentially of a switch, which is formed in a first embodiment as a poppet valve and in a second embodiment as a conventional flap. This switch releases the exhaust gas inlet into the exhaust gas cooler, thereby closing the bypass line or opening the bypass line and at the same time closing the exhaust gas inlet. A division into defined partial exhaust gas streams is not possible with this switching device.
  • the invention is therefore an object of the invention to make a generic switching device such that in a cost effective manner and with low installation dimensions of the above drawback is avoided.
  • the switching element is a hollow body having an axis of rotation, which allows pivoting of the hollow body, such that a continuous adjustment of the exhaust gas inlet is ensured in the exhaust gas cooler and the bypass line.
  • the axis of rotation is concentric with the exhaust pipe, wherein the hollow body is designed substantially as obliquely cut cylinder tube having an exhaust gas inlet opening in the base and an exhaust outlet opening in the region of the side surface with the longest generatrix and is arranged in the manifold. It is advantageous if the manifold is designed substantially Y-shaped with an exhaust gas inlet region and two Abgasauslledge Symposiumen.
  • the axis of rotation extends perpendicular to the exhaust pipe, wherein the hollow body is designed substantially as a rotary cylinder with a through hole and is arranged in the exhaust pipe. It is again particularly advantageous if the manifold is designed substantially V-shaped with two exhaust gas outlet, wherein a web element between the exhaust gas outlet serves as a stop piece for the rotary cylinder.
  • a control member is rotatably arranged, such that the size of the passage opening is variable.
  • this embodiment is structurally particularly simple to make when the control element has the same axis of rotation as the rotary cylinder.
  • FIG. 1 shows an exhaust gas recirculation 1 for an internal combustion engine 2.
  • an exhaust pipe 3 which leads to an exhaust gas via a turbine 4 to the outside and on the other, as described below, exhaust via a switching device 5 for exhaust gas recirculation back to the engine 2 passes ,
  • a compressor 6 is driven, the compressed ambient air and a charge air line 7, which has a charge air cooler 8, supplies.
  • the charge air line 7 then leads to the charge air distributor rail 9 of the internal combustion engine 2.
  • the exhaust pipe 3 opens, as already indicated above, to a switching device 5, which makes it possible to lead the exhaust gas through an exhaust gas cooler 10 via an exhaust gas cooler 11 or through a bypass line 12 to an exhaust gas recirculation valve 13, which in a known manner the introduction of exhaust gas in the intake air of the internal combustion engine 2 controls.
  • FIG. 2 shows a sectional view of a first embodiment of the switching device according to the invention 5.
  • This switching device 5 consists essentially of a manifold 13 with an exhaust gas inlet region 14 which is connected to the exhaust pipe 3 and two exhaust gas outlet regions 15, 16, each with the exhaust gas cooler line 10 and the bypass line 12 are connected and designed as a hollow body switching element 17.
  • the manifold 13 is advantageously formed Y-shaped.
  • the hollow body 17 has substantially the shape of an obliquely cut cylinder tube with an exhaust gas inlet opening 18 in the base and an exhaust outlet opening 19 (s. FIG. 3 ) in the region of the side surface with the longest generatrix of the obliquely cut cylinder tube 17.
  • the hollow body 17 can be driven in a known manner by a rotation axis 19 which extends through the manifold 13 and extends concentrically to the exhaust pipe 3.
  • the switching element which is designed as obliquely cut cylinder tube 17 is shown in a side view in FIG. 3 shown. Clearly visible here is the exhaust gas outlet opening 19 in the region of the side surface with the longest generatrix.
  • FIG. 4 shows the sectional view of a second embodiment of the switching device 5 according to the invention.
  • designed as a hollow body switching element 17 is designed as a rotary cylinder.
  • the rotary cylinder 17 has a passage opening 21 (s. FIG. 5 ), which, depending on the position of the rotary cylinder, the exhaust gas of the exhaust pipe 3 into the exhaust gas cooler line 10 and / or the bypass line 12 leads.
  • the axis of rotation 20 of the rotary cylinder 17 extends in the present embodiment perpendicular to the exhaust pipe. Furthermore, it is possible to mount the rotary cylinder 17 directly in the exhaust pipe 3.
  • the manifold 13 is formed in this case V-shaped and has two exhaust gas outlet 15 and 16, which - as already described above - are connected to the exhaust gas cooler line 10 and the bypass line 12.
  • the exhaust outlet 15, 16 are separated in the present embodiment by a web 22, which also serves as a stop piece for the rotary cylinder 17 to set the rotary cylinder 17 in a defined end position.
  • FIG. 5 shows the rotary cylinder 17 again in a single view. Clearly visible is the passage opening 21st
  • FIG. 6 now shows a further embodiment of the switching device according to the invention.
  • a control member 23 which may be designed as a cylinder segment is arranged.
  • the size of the through hole 21 can be changed in this way.
  • a particularly simple embodiment is when the control member 23 has the same axis of rotation 20 as the rotary cylinder 17th
